I just transferred all my stuff from my old Nintendo 3DS to a brand new Nintendo 3DS XL and I have just noticed that none of my stuff from Mii Plaza's "Puzzle" game have transferred. I have the puzzles from "Metroid M" to "Super Mario Bros. Wii" but my other SD card, the one that was in my old 3DS, still has the other puzzles such as "Sonic Boom", "Kirby's 20th Anniversary" and other stuff. I wanted to transfer this data to a much larger SD card (one my friend gave me).
Why did this part not transfer? I also seemed to not be able to make new data for my Street Pass on my 3DS XL when I went into it today. I was able to re-download the software that transferred with my eShop and bought Themes. If someone can help me ASAP, that would be great. Trying to call the Nintendo Help Line did not help and I don't think I got quite my answer from a live chat. The live chat representative thinks I didn't transfer the SD card to the new system after. I thought that meant, no matter what, you couldn't use another SD card with a system.
